不过不止这种方式，粒子还有另外其它三种衰变方式。
Not only that, but there are three ways that particles can decay.
不同衰变方式和半衰期的放射性核束在生物医学领域有不同应用。
Radioactive ion beams with different decay modes and half-lives can be applied in many aspects of bio-medical fields.
我们发现的第一种衰变方式——阿尔法衰变——是放射性粒子产生氦分子！
The first type discovered -- alpha decay -- is when a radioactive particle emits a Helium nucleus !
探测器检测出由它们的衰变方式决定的特征信号并记录下来，这些数据随即由科学家们进行分析。
The detector picks up the telltale "signatures" of these decay patterns and records them, and the data is then analyzed by scientists.
但是普渡大学的一组研究者用意想不到的方式挑战了衰变速率恒定这个假设。相比于原子核衰变，他们对随机数更感兴趣。
But that assumption was challenged in an unexpected way by a group of researchers from Purdue University who at the time were more interested in random Numbers than nuclear decay.
在衰变周期的特殊的点上每一种不同的供养方式，会产生从2 - 100中不同的生物酶。
Each specializes in feeding at specific points in the cycle of decay, and can have anywhere from two to 100 different enzymes.
